I've used it all the time. Y0u pretty much have to use launch control / remove traction control with my power levels or it would clamp on the brakes to control wheel spin = slower.

Maybe you've been lucky. Maybe not.

I had a '99 Pontiac Grand Prix GTP with mods. Those cars had problems with the differentials. If you did a lot of "one-wheel wonder burnouts" with them, one of the roll pins in the differential was prone to drop out and grenade the differential, taking the whole trans with it. A guy I was stationed with in Hawaii had it happen to his '98 GTP. The service adviser at the dealership just looked the other way on his mods and accepted it for warranty.

...and that may well happen at least as often as you hear about dealerships voiding warranties for mods. It's a roll of the dice. Either way, if I mod and break something, I'm not going to try and hide my mods and take it in for warranty work. To me, that's crossing a line.

In most cases it isn't up to the dealership anymore. Chrysler like nearly all OEMs now have a regional rep that comes in and approves major repairs. Or not. He doesn't care how good a customer you are because he doesn't sell cars. He is highly trained, very experienced, and possess no mercy. If he does not approve the repair the dealership cannot get reimbursed for labor and will have to buy the parts for the repair on their own dime. That is assuming you're such a good customer that the dealer is willing to come out of pocket for that major repair. My guess would be very few people here are and I know I'm not.

Once that happens possession is 9/10s of the law and you are not in possession of your warranty. When you face denial you are out of pocket or broke down till the end of a long process that isn't any fun and may cost more than even a very large repair. Further while the MM act says you can ask for fees there is no guarantee you will be awarded them even if you win. Don't even think of telling them they have to fix it because the MM act says they have prove your shiny little gadget caused or contributed to the breakdown unless you enjoy being laughed at.

I'm not going to say to anyone that they should not mod their vehicles. I myself haven't had a car I kept stock my entire life but I went in eyes open. I can tell you one thing though, no matter how careful you are should you play the performance game there may be carnage. I'm not saying there will be but there may be. The saying over in corvette land is if you want to mod your car you should be prepared to be your own warranty station. It's true here as well, if you are not capable of and willing to pay for every part that makes your car move you should probably take a moment to consider if you really want to go forward.

Sorry I couldnt quote your post, something is not right with my browser right now and everything is messed up

How is the ECU going to detect and log out of spec HP and TQ numbers? With out a brake dyno there is no way to determine that information. The load that the engine sees on a dyno is how those numbers are calculated, and there is no load sensor on a passenger vehicle. I just dont see how they could do it.

Now, they could read out of spec parameters, like fuel rail pressure too high, or too much boost from the turbo, but that would imply an open loop system with control feedbacks, which are very expensive and difficult to maintain properly. The only place I can think of on a passenger car engine that uses an open loop system is the Oxygen sensors on a OBD2 platform vehicle where you have a pre and post cat sensor to make sure that the cat is functioning properly. But that isnt even truly an open loop system as it cant control itself.

I just cant see where the ECU is going to get the "I caught you" information from unless there is some other sensor in the system that provides a reference value.

My understanding of the piggyback box is that it is going to plug into the sensor that provides the control of the sensor, and also is used as a reference. If the signal out of the ECU goes thru the tuner box and into the tuner, it has to return to the tuner box, which will then "wash" the signal for return to the ECU, otherwise the ECU throws a code and shuts you down.

I just cant see where the ECU is going to get the information that something has changed. It is seeing what it is supposed to see and not throwing a code, therefore there is nothing to log.

Bob that is exactly how it works. Without some sort of "power sensor" like an engine dyno, there is no way to log anything. As long as you remove the piggy back before warranty work, you will be fine. I like knowing I am using the full power of the diesel and not the de-tuned version for emissions. I am willing to take whatever little risk there is with that. Some may rightfully not be comfortable with that.

Bluespark Pro + Boost installed. It took 10 minutes. I could do it in 3 minutes now.

First impression on the default setting...wow! In Sport mode...it was aggressive. It really wakes up an already willing and peppy motor. I'm still breaking mine in at 980 miles so I won't be turning it up any time soon.

No check engine at WOT so I'll drive it a bit and see if mpg is improved any.

2nd impression....torque comes on earlier. I can hear the "swish" of the turbo pulling a mild grade in 8th at 1300 rpm. A standing start in sport mode made the back end squat hard and she aggressively went to 60 noticeably quicker. This is in stock B5 setting. It has 5 maps....A to E and a rotary fine tune 1-9 dial.

Light throttle cruise is as refined as before with addition of extra grunt at lower rpm.

The engine has a little more diesel cackle like a big truck. I like it. Before it was "too quiet". I like to hear it a little since I'm a long time diesel driver.

The Bluespark delivers folks. I feel like it unleashed the beast.

It came with installation sheets. There is a description of the settings and how the interact but no curves.

Curves or not, the difference is significant. I would like to see curves also.
